Cavian (3.5)
A sourcebook introduces the Cavians, a race of humanoid rodents with powerful psionic abilities and a collective hive mind. Recently returned from nearly three centuries of exile, they inspire unease among other peoples unfamiliar with their gifts. The supplement provides rules for playing a Cavian character, including personality and relations, along with a Cavian paragon class, new feats such as Hive Mind and Severed, and a blank Cavian character sheet.
